  • Publication number: 20070055087
    Abstract: A method for utilizing whole crude oil as a feedstock for the pyrolysis furnace of an olefin production plant wherein the feedstock is subjected to vaporization conditions until substantially vaporized with minimal mild cracking but leaving some remaining liquid from the feedstock, the vapors thus formed being subjected to severe cracking in the radiant section of the furnace, and the remaining liquid from the feedstock being mixed with at least one quenching oil.

  • Publication number: 20050107698
    Abstract: A shielded radioactive medical apparatus has a tubular housing with a quick release cap configured for closing an open end of the tubular housing. A quick release mechanism holds the quick release cap on an open end of the tubular housing. A data display module on the housing communicates with an outside computer for receiving and transmitting information. The data display model also calculates and displays the radioactivity of a dose within the housing.

  • Publication number: 20050043574
    Abstract: A method for making propylene from alpha olefins, internal linear olefins and isoolefins wherein the alpha olefins are subjected to a combination of hydrogenation and double bond isomerization to form additional internal linear olefins, the internal linear olefins are disproportionated with ethylene to form a propylene product, while the isoolefins are subjected to skeletal isomerization to form yet additional internal linear olefins to be converted into yet additional propylene.

  • Patent number: 6630589
    Abstract: The invention features screening assays for compounds that are potentially useful for treating or preventing a proliferative disease. The assays are based on contacting a candidate compound with a cell containing a nucleic acid including a HER2 regulatory element and a reporter sequence. In addition, the invention features compounds identified by the assays of the invention. The invention further features compounds structurally related to those identified by the screening assays. Finally, the invention features methods of treating or preventing a proliferative disease using the compounds of the invention.

  • Patent number: 6203572
    Abstract: A device is disclosed for delivery of grafts such as, for example, semitendinosus and/or gracilis tendons for reconstructive surgery. The device is a woven structure whose diameter is reduced when placed in tension. It has a tapering end and an open end. A suture is looped within the device so that the loop extends from the open end to receive the folded graft. The suture is pulled to insert the graft into the device. The graft, after folding and being pulled into the device, may have sutures extending out of one end as an optional feature to facilitate subsequent fixation. The sutures extending through the tapered end are pulled, tightening the device around the graft while pulling the device with the graft inside through the bone tunnels such as, for example, tibial and femoral tunnels. The narrow tapering end traps the graft as the device tightens around the graft for insertion into the tunnels.
